Signal Pod Wireless Bicycle Signalling System, £19.36, Amazon.
The Signal pod is a wireless bicycle signalling system, designed for extra
safety while cycling. Maintain full control of your bike - your hands will
never leave the handlebars, as the Signal Pod control unit conveniently
clips on. With three settings, clear LED arrows light up to indicate 'left',
'right' and 'hazard' much like a car or motorcycle would, and the audible
beeps alert pedestrians and nearby motorists.
